Why Do They Do Studies Like This?

A recently published study claims to have shown that a proprietary mixture of velvet bean and Chlorophytum borivilianum improves sleep quality. The journal, Integrative Medicine Insights, is online, peer-reviewed, PubMed indexed, open-access, and it charges authors $1848.00 to publish their article. It advertises editorial decisions in 3 weeks and publication in 2 weeks after acceptance. I can see two reasons why authors might be willing to pay that much for publication: to speed the process of getting important research results out to the public, or because their research is poor quality and they know it would be rejected by other journals.

The quality of this study is unfortunately typical of much of the research on alternative medicine.

They also measured heart rate, blood pressure, CBC, metabolic panel, and lipid panels.
